disable the test that's broken upstream

mysql-test/suite/innodb/include/restart_and_reinit.inc:
  drop and recreate mysql.innodb* tables when deleting innodb table spaces
mysql-test/t/ssl_8k_key-master.opt:
  with loose- prefix ssl errors are ignored
sql-common/client.c:
  compiler warnings
sql/field.cc:
  use the new function
sql/item.cc:
  don't convert time to double or decimal via longlong,
  this loses sub-second part.
  Use dedicated functions.
sql/item.h:
  incorrect cast_to_int type for params
sql/item_strfunc.cc:
  use the new function
sql/lex.h:
  unused
sql/my_decimal.h:
  helper macro
sql/sql_plugin.cc:
  workaround for a compiler warning
sql/sql_yacc.yy:
  unused

  fix the merge for SERVER_STATUS_IN_TRANS_READONLY protocol flag
storage/sphinx/CMakeLists.txt:
  compiler warnings

and small collateral changes

mysql-test/lib/My/Test.pm:
  somehow with "print" we get truncated writes sometimes
mysql-test/suite/perfschema/r/digest_table_full.result:
  md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/perfschema/r/dml_handler.result:
  host table is not ported over yet
mysql-test/suite/perfschema/r/information_schema.result:
  host table is not ported over yet
mysql-test/suite/perfschema/r/nesting.result:
  this differs, because we don't rewrite general log queries, and multi-statement
  packets are logged as a one entry. this result file is identical to what mysql-5.6.5
  produces with the --log-raw option.
mysql-test/suite/perfschema/r/relaylog.result:
  MariaDB modifies the binlog index file directly, while MySQL 5.6 has a feature "crash-safe binlog index" and modifies a special "crash-safe" shadow copy of the index file and then moves it over. That's why this test shows "NONE" index file writes in MySQL and "MANY" in MariaDB.
mysql-test/suite/perfschema/r/server_init.result:
  MariaDB initializes the "manager" resources from the "manager" thread, and starts this thread only when --flush-time is not 0. MySQL 5.6 initializes "manager" resources unconditionally on server startup.
mysql-test/suite/perfschema/r/stage_mdl_global.result:
  this differs, because MariaDB disables query cache when query_cache_size=0. MySQL does not
  do that, and this causes useless mutex locks and waits.
mysql-test/suite/perfschema/r/statement_digest.result:
  md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/perfschema/r/statement_digest_consumers.result:
  md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/perfschema/r/statement_digest_long_query.result:
  md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/rpl/r/rpl_mixed_drop_create_temp_table.result:
  will be updated to match 5.6 when alfranio.correia@oracle.com-20110512172919-c1b5kmum4h52g0ni and anders.song@greatopensource.com-20110105052107-zoab0bsf5a6xxk2y are merged
mysql-test/suite/rpl/r/rpl_non_direct_mixed_mixing_engines.result:
  will be updated to match 5.6 when anders.song@greatopensource.com-20110105052107-zoab0bsf5a6xxk2y is merged

Next step of merge

storage/myisam/mi_create.c:
  Merge from 5.6

        The flag is now checked for MYSQL_LOCK_LOG_TABLE and similar
        in open_table().

per-file comments:
  sql/sql_base.cc
        MDEV-495 Table logging does not work in TRANSACTION READ ONLY mode.

and SET TRANSACTION READ ONLT|READ WRITE
statements.


per-file comments:
  mysql-test/include/check-warnings.test
        READ ONLY transaction flag cleaned.
  mysql-test/r/commit.result
        result updated
  mysql-test/r/read_only.result
        result updated
  mysql-test/t/commit.test
        tests added.
  mysql-test/t/read_only.test
        tests added
  sql/lex.h
        ONLY symbol added.
  sql/sql_base.cc
        DBUG_RETURN added.
  sql/sql_parse.cc
        implementations added.
  sql/sql_yacc.yy
        SQL syntax extended.
  storage/perfschema/gen_pfs_lex_token
        changes forced by lex.h
  storage/perfschema/pfs_lex_token.h
        changes forced by lex.h

Added missing system tables used in 5.6

Moved timestamp handling from all handler::write() methods in the storage engines to handler::ha_write

sql/handler.cc:
  Added PSI_CALL's

Fixed wrong error codes from InnoDB/XtraDB that caused %M to give system dependent error messages (for unknown error code)
- InnoDB now returns handler specific HA_WRONG_CREATE_OPTION instead of MySQL specific ER_ILLEGAL_HA_CREATE_OPTION
- This changes the user level error message from "Unknown error" to "Wrong create options"


mysql-test/r/lowercase_table2.result:
  Updated result file
mysql-test/r/partition_innodb_plugin.result:
  Updated to new error message
mysql-test/r/partition_open_files_limit.result:
  Updated result file
mysql-test/r/row-checksum-old.result:
  Updated to new error message
mysql-test/r/row-checksum.result:
  Updated to new error message
mysql-test/r/symlink.result:
  Updated result file
mysql-test/suite/innodb/r/innodb-create-options.result:

mysql-test/suite/innodb/r/innodb-zip.result:
  Updated to new error message
mysql-test/suite/innodb/r/innodb.result:
  Updated to new error message
storage/innobase/handler/ha_innodb.cc:
  Return HA_WRONG_CREATE_OPTION instead of ER_ILLEGAL_HA_CREATE_OPTION
  This gives more clear and OS indepedent error messages
storage/xtradb/handler/ha_innodb.cc:
  Return HA_WRONG_CREATE_OPTION instead of ER_ILLEGAL_HA_CREATE_OPTION
  This gives more clear and OS indepedent error messages

client/mysqltest.cc:
  Added cast
plugin/feedback/utils.cc:
  Added #ifdef
sql/sql_select.cc:
  Added cast
sql/sys_vars.h:
  Changed limits to int
support-files/compiler_warnings.supp:
  Added suppression

Fixed failing test case

- Better error messages

This fixes that one again can run the test systems with many threads without having to increase fs.aio-max-nr.


mysql-test/include/mtr_check.sql:
  Ignore the INNODB_USE_NATIVE_AIO variable (may change during execution)
mysql-test/mysql-test-run.pl:
  Ignore warnings for failure to setup AIO
storage/innobase/os/os0file.c:
  Continue without AIO even if we can't allocate resources for AIO
storage/xtradb/os/os0file.c:
  Continue without AIO even if we can't allocate resources for AIO
storage/xtradb/srv/srv0start.c:
  Give an error message (instead of core dump) if AIO can't be initialized

The bug was the result of the incomplete fix for bug lp bug 1008293.

the new file is fully synced to disk and binlog index. This fixes a window
where a crash would leave next server restart unable to detect that a crash
occured, causing recovery to fail.

MDEV-359: Fix another case where switch-off semisync could cause a race that ended with server crash.

This one was when the code releases and reaquires the lock with pthread_cond_wait() - and semisync is switched off meanwhile.

The semisync code does a fast-but-unsafe check for enabled or not without lock,
followed by a slow-but-safe check under lock. However, if the slow check failed,
the code still referenced not valid data (in an assert() expression), causing a
crash.

Fixed by not running the incorrect assert when semisync is disabled.

This is XtraDB bug lp:1015109, introduced by innodb_split_buf_pool_mutex.patch

Comment the offending assertion, until the fixed XtraDB is available
